DUPLICATING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 778,415, dated December 27, 1904.

Application filed March 30, 1904.. Serial No. 200,857.

To aZZ whom, it may concern:

Be it known that we, AUGUSTUS D. KLABER, a subject of the King of Great Britain, and WILLIAM D. STERNBERG, a citizen of the United States, both residing at London, England, have invented a certain new and useful Improvement in Duplicating Apparatus, of which the following is a specification.

The object of the present invention is to provide a stencil-duplicating apparatus'or outfit which shall be compact and yet complete, containing within itself all the necessary mechanism and appliances for the production of multiple copies from a stencil-sheet. A further object is to so arrange such mechanism or appliances within a suitable inclosing case as that every part thereof shall be guarded against accidental injury when such case is closed, but be moved to operative position upon the opening of such inclosing case for the performance of, such duplicating operation.

In carrying out the invention We employ a suitable base to which in a preferred form is hinged a two-part inclosing case, said base and said inclosing case between them supporting the inking-slate, theStenCil-frarhe, and thetopsheet frame, and, if desired, a portfolio for the reception of stencil-sheets or impression-paper andcoacting with the inking-slate an inking-roller and an ink-reservoir or other source of ink-supply. These are so supported within the base and frame as that when the latter is closed they will be separated from injurious contact with each other, Whereas upon opening said inclosing case the parts will without requiring further attention from the operator automatically assume operative 7 position.

Theinvention is illustrated in the accompanying-drawings, in which Figure 1 is a top plan view illustrating the duplicating apparatus referred to, the inclosing case being open. Fig. 2 is a cross-section on the line 2 2, Fig. 1, the closed position of the parts being illustrated in dotted lines. Fig. 3 is an enlarged detail illustrating the manner in Which the stencil and top-sheet supports may be hinged to the base. Fig. 4 is a crosssection on the line 4 4,-Fig. 1., on an enlarged scale, however. Fig. 5 is a plan view illustrating the glass, plate and its supportingframe, and which plate is designed to receive the impression-paper to be printed upon. Fig. 6 is an under side View of the stencil and topsheetsupporti'ng frame, showing the stencilsheet secured in position thereto. cross-section taken through the line 7 7 Fig. 6, illustrating the stencil and top-sheet-supporting frame and the clamp coacting therewith to secure the stencil-sheet in position;

Fig. 7 is a and Fig. 8 is a detail view of the inking-roller support looking in the direction indicated by the arrow, Fig. 1.

Referring to the drawings, in which similar letters denote corresponding parts, A designates the base, provided adjacent to each end withthe brackets a. To this supporting-base are hinged at?) c the members of the sectional casing B O, each comprising a bottom and three sides. These members B O of the c'as.

ing are capable of being moved together (in the closed position of the apparatus) and may be provided with a securing meansas, for instance, the latch D, coacting with pin d.

E designates the inking-slate, pivoted at e to the bracket a of the base A. Near its outer corners this slate is provided with pins '6, coacting with slots 6 for-med in oblique guides 6 As shown in Fig. 2, when the parts assume open position, the pins eride out of the slots 6 thereby supporting the outer end of the slate upon the sides of said guides. If desired, however, the under side of the slate may be provided with a gravityfoot 6, (illustrated in dotted lines, Fig. 2,) which will fall when the parts assume this position, and thereby not only support the outer edge of the inking-slate, but also coact with the prints fed into the casing to the left of such foot, as hereinafter described.

F designates the inking-roller, provided with the handle f.

G designates a bracket secured to the surface of the inking-slate (or to the frame formingpart of suchslate) and provided with an opening 9 and slot 9.

To secure the roller in position after using, the neck of the handle f may be introduced through the opening 9 and then pressed into the slot g, so as to be securely retained therein by means of the lip g H designates an ink-can. This is detachably mounted between two heads it It, said heads being secured together by means of the screws h Operating through the head It is a screw it, coacting with a threaded perforation in said head and provided at its end with disk 71 which bears against the movable top it of the ink-can H.

The head it is provided with an opening it, communicating with a passage 7L5, which in turn communicates with a tube 7L6, terminating in an orifice b in the inking-slate. Secured to the inking-slate or to the frame thereof is a spring-plate it whose end terminates over the orifice 7L7. To supply the slate with ink, the screw ha is turned so as to expel a quantity of such ink from the can H and pass it through the tube it, and thence to the slate through the orifice If against the pressure of the spring-plate lb I designates the printing-plate, (preferably of glass and mounted in a frame z',) pivoted at a" to the bracket o of the base A. The under side of said frame and plate may support a portfolio 2' held in position by clips i carried by said frame.

L designates the stencil and top sheet frame, here shown as made in two parts Z Z, between which is secured the top sheet Z, the edges thereof being confined between the members Z Z of said frame. Said parts are secured together by means of the clamps Z Said stencil and top-sheet frame is pivoted at Z to an arm Z carried by the frame 2' of the printing-plate I. iWIounted upon the pivot l and coacting with the under side of the stenoil and top-sheet frame is a spring Z exerting a tendency to separate the frame L from the printing-plate I.

Preferably a latch and pin Z 1 will be provided to secure the frame L and the frame 2' together as against the tendency of said spring to separate them. If desired, there may be one of the springs Z at each end of the stencil and top-sheet frame.

M designates the stencil-sheet clamp, here shown as pivoted at Z and having an angular end on, which engages with the edge of the frame L to secure said stencil-sheet clamp in position. If desired, the upper surface of said clamp M may be provided with a series of teeth, bosses, or other projections m, with which may coact similarly-spaced perforations formed in the end of the stencil-sheet m To secure the stencil-sheet in position, the outer angular end an may be disengaged from the frame L and said frame raised, whereupon the stencil-sheet may be placed in position with the pins m projecting through the perforations in the end thereof, whereupon the clamp may again be engaged with the frame L. If desired, the distant end of this stencilsheet may be secured in any suitable manner to the frame L, although we do not consider this strictly necessary, as the same will be held in position by ink transmitted thereto, as hereinafter described.

The frame '21 of the printing-plate I, like the inking-slate on the under side of the apparatus, may be provided with pins 1", coacting with slots 1 formed in oblique guides i In operation a stencil-sheet is secured in position in the manner above indicated and the sheet of impression-paper, upon which the imprint is to bemade, is laid upon the plate I. The two-part frame carrying the top sheet and stencil-sheet is then pressed dmvnwardly upon said plate, and the roller, previously provided with ink, passed over such top sheet in order to force the ink through the same and through the interstices in the stencil-sheet to the surface of the impression-paper below. On ceasing to press the top-sheet and stencil-sheet frame downwardly, the same will be raised by the springs I and the sheet of impression-paper will follow the same a certain distance. As said frame assumes its upper position, however, the impression-sheet will slip therefrom and pass between said steneil-sheet frame and the printing-plate frame into the receptacle formed by the member C of the casing below the printingplate. If desired. theunder side of the printing-plate I may be provided with a registering-sheet, which may be adjusted with reference to the stencil cut upon the stencilsheet and fixed in such adjusted position by any suitable means as, for instance, an elastic band. Thereafter the inipression-paper may be laid on the upper surface of said plate directly over said registering-sheet and the position of the impression thereon accuralrly determined.

hat we claim, and desire to secure by Letters Patent, is as follows:

1. In duplicating apparatus, the combination with a base, of a two-part inelosing case pivotally connected with said base at either side thereof, and a stencil-frame pivotally mounted therein, substantially as set forth.
